Expressionism is strongly light-biased - shadow is suggested rather than declared. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The saturated accent, #AF4B2A, registers at 4.4% - sparse enough to feel like a deliberate surprise. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities point to the open-air Impressionist method: recording light rather than local colour.
